Each example will include discussion of design value adjustment factors and load combinations.

Learning Objectives
Upon completion of this webinar, participants will:

Proper design of wood structures to resist high wind loads requires the correct use of wind load provisions and member design properties. A thorough understanding of the interaction between wind loads and material properties is important in the design process. Adjustments from reference wind conditions to extreme-value peak gusts require designers to make similar adjustments to design properties to ensure equivalent and economic designs. Wind load provisions have been developed for design of major structural elements using Main Wind-Force Resisting System (MWFRS) loads and secondary cladding elements using Component & Cladding (C&C) loads. Elements and subassemblies which receive loads both directly and as part of the main wind force resisting system, such as wall studs, must be checked independently for MWFRS loads and C&C loads. A load bearing stud wall design example based on the allowable stress design methods outlined in AWC's 2015 National Design Specification® (NDS®) for Wood Construction and 2015 Wood Frame Construction Manual along with ASCE 7-10 Minimum Design Loads for Buildings and Other Structures will demonstrate standard design checks for limit states of strength and deflection.

A range of structural elements are included such as sawn lumber, structural glued laminated timber, wood structural panel sheathing, I-joists, and trusses.

Part 4 will focus on the first-story design and include summation of loads from above and connections specific to foundations.

Learning Outcomes

Upon Completion of this course, participants will:

Learn the appropriate high wind, seismic, and snow loads to apply to residential structures based on code-referenced load standards.

Learn about the engineering basis of prescriptive tables used to size wood members and connections to resist high wind, seismic, and snow loads.

Learn to use prescriptive tables to size wood members and connections to resist high wind, seismic, and snow loads.

Learn to use checklists and detailing summaries to ensure a complete load path is prescriptively designed.

The 2015 Wood Frame Construction Manual (WFCM) is referenced in the 2015 International Building Code and 2015 International Residential Code. For WFCM load calculations, Minimum Design Loads for Buildings and Other Structures (ASCE 7-10) is used. The 2015 WFCM includes design information for wind and seismic loads and gravity loads including snow, roof live, floor live, and dead loads on buildings up to 3 stories. This presentation will provide background and examples for calculation of forces on headers which will enable designers and code officials to quickly determine design loads. It will also provide engineered prescriptive solutions for both solid sawn and glued-laminated timber headers to resist those loads. Related issues including jack studs, king studs, connections for lateral and gravity loads, and the difference between dropped and raised headers will be discussed.

Upon completion of this webinar, participants will:

Understand applicable lateral and gravity loads from ASCE 7-10 for headers within the WFCM scope.

Be familiar with the difference between dropped and raised headers.

Be familiar with the design of jack studs and king studs to resist both gravity and lateral loads.

Be familiar with the design of lateral, shear, gravity, and uplift connections related to headers.

The Wood Frame Construction Manual (WFCM) for One- and Two-Family Dwellings (ANSI/AWC WFCM-2018) has been updated and is referenced in the 2018 International Building Code (IBC) and 2018 International Residential Code (IRC). The 2018 WFCM uses gravity and lateral loads based on ASCE 7-16 Minimum Design Loads and Associated Criteria for Buildings and Other Structures. This presentation will provide an overview of the significant changes in the 2018 WFCM relative to the previous 2015 edition. The WFCM provides code officials and designers with time-saving tools based on engineered and prescriptive solutions (based on structural engineering principles) for wood structures to resist anticipated lateral and gravity loads.

Learning Objectives

Be familiar with provisions of the 2018 WFCM and relevant references in the 2018 IRC and 2018 IBC

Be familiar with changes to the 2018 WFCM and their impact

Understand new wind provisions based on ASCE 7-16

Understand the addition of deformed-shank fasteners and other criteria to address new wind load provisions

Per the International Building Code (IBC), structures using wood shear walls and diaphragms to resist wind and seismic lateral loads shall be designed and constructed in accordance with AWC's Special Design Provisions for Wind and Seismic (SDPWS). This course will discuss the 2015 SDPWS which is a dual format document with both allowable stress design (ASD) and load and resistance factor design (LRFD). In this course, participants will learn about format of the SDPWS and how to apply design provisions to shear walls and diaphragms as well as changes from previous editions.

Upon Completion of this course, participants will:

Be able to understand load path basics and how it applies to wood structural design.

Be familiar with the significant changes between the 2008 and 2015 SDPWS.

Be able to identify lateral resisting systems and understand where to obtain design specifications for these systems.
